SPECIFICATION formingpart 0f Letters Patent No. 497,328, dated May 16, 1893.

Application fled October 14, 1892. Serial No. 448,887.v (No model.)

To @ZZ whom it may concern:

Be it known that I, HIRAM LEMM, a resident of Storm Lake, in the county of Buena Vista and State of Iowa, have invented certain new and useful Improvements in Whifletree-Hooks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in whiffletree h0oks,-the object of the invention being to produce a whittletree hook constructed and attached to the whffletree in such manner that when the draft slackens or the tug drops down the hook will move in unison therewith without dan gerof becoming detached from the tug.

` A further object is to produce a whifietree hook which shall be simple in construction and eectnal in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out in the claim.

In the accompanying drawings: Figure l, is a side view of my improved hook showing the manner ot' attaching the tug thereto. Fig. 2 is a sectional view of a portion of a whiflletree having my improvement applied thereto. Fig. 3 is a view of a modification.

A represents the whitl'letree having a head or collar a, formed at the ends thereof. A sleeve b is placed on the whiffletree adjacent to the collar or enlargement a.

My improved hook B is made at one end with a loop or opening c for the reception of the sleeve or ferrule'b, one face of said loop being adapted to lie adjacent to thev collar or enlargement a. After the hook B is thus placed on the sleeve or thimble b on the end of the Whiftletrce,a collar d is placed on said sleeve adjacent to the loop c at the opposite side thereof from the collar or enlargement a said collar d being secured to the sleeve or ferrule b in any suitable manner. By thus attaching the hook to the whiflietree it will be permitted to have a free oscillatory motion and will be prevented from lateral movement -in Fig. l.

by the collars a, d. The free end `e of the hook is made to extend under the whifetree and to partially embrace the same without` contact therewith and at its extremity is preferably provided with a head or enlargement f.- The buckle g to which the haine tug is connected, is attached to the hookB as shown From this construction and arrangement of parts it will be seen that when the draft isrelaxed or diminished the tug will fall somewhat, and that the hook B will be free to turn on the whiiietrce in unison with the movement of the tug, and that owing to theconstruction of the hook the detachment of the parts will be effcctually prevented. Thus the hook B will be free to yield to the movements of the tug. The portion c of hook Bis made heaviest so that it will fall freely.

Instead of connecting the hook to the whiffietree as above explained, the construction shown in Fig. 3 may beV adopted,-in which case the butt end of the hook will be provided with a perforation through which a pin or screwj passes, the latter being secured to the end of the whiflietree. Itis of course understood that each end of thewhiiletree will be provided with myimprovements and that the device is also applicable to neck yokes and other like devices.

The device is simple in construction, cheap to manufacture and effectual in the performance of its functions. y

Having f nlly described my invention, what I claim as new, and desire to secure by Letters Patent, is

As an article 0f manufacture, a whiftletree hook consisting essentially of a body portion adapted Vt0 be attached to the Whiftletree, a.

around the whifIiet-ree concentric with the latf ter, substantially as set forth. y

In testimony whereof I have signed this specification in the presence ofv two subscribing witnesses.

' HIRAM LEMM.
